From d4703aefdbc8f9f347f6dcefcddd791294314eb7 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Tue, 15 Dec 2009 16:28:32 -0600 Subject: module: handle ppc64 relocating kcrctabs when CONFIG_RELOCATABLE=y powerpc applies relocations to the kcrctab. They're absolute symbols, but it's not completely unreasonable: other archs may too, but the relocation is often 0. http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-November/077972.html Inspired-by: Neil Horman Signed-off-by: Rusty Russell Tested-by: Neil Horman Acked-by: Paul Mackerras --- arch/powerpc/include/asm/module.h | 5 +++++ arch/powerpc/kernel/vmlinux.lds.S | 3 +++ 2 files changed, 8 insertions(+) (limited to 'arch/powerpc') diff --git a/arch/powerpc/include/asm/module.h b/arch/powerpc/include/asm/module.h index 08454880a2c0..0192a4ee2bc2 100644 --- a/arch/powerpc/include/asm/module.h +++ b/arch/powerpc/include/asm/module.h @@ -87,5 +87,10 @@ struct exception_table_entry; void sort_ex_table(struct exception_table_entry *start, struct exception_table_entry *finish); +#ifdef CONFIG_MODVERSIONS +#define ARCH_RELOCATES_KCRCTAB + +extern const unsigned long reloc_start[]; +#endif #endif /* __KERNEL__ */ #endif /* _ASM_POWERPC_MODULE_H */ diff --git a/arch/powerpc/kernel/vmlinux.lds.S b/arch/powerpc/kernel/vmlinux.lds.S index 27735a7ac12b..dcd01c82e701 100644 --- a/arch/powerpc/kernel/vmlinux.lds.S +++ b/arch/powerpc/kernel/vmlinux.lds.S @@ -38,6 +38,9 @@ jiffies = jiffies_64 + 4; #endif SECTIONS { + . = 0; + reloc_start = .; + . = KERNELBASE; /* -- cgit v1.2.2
